I revived a few RPTVs and the time and trouble only taught me that it was time to move on.
http://www.techlore.com/forum/thread/18552/Can-you-tell-me-what-is-wrong-with-my-TV-/ is an interesting reading since it was the same failure I fixed more than once. Not for the timid or folk without a strong electronics background I fear.
We have had the subject TV for about 11 years. This morning when we turned on the set the picture was noticeably darker than usual and then proceeded to get even darker as time went on. After about an hour or so it was completely black. I shut it off and tried it later in the day and it is completely black right at start up - no picture at all. The sound still works fine. I tried multiple inputs to make sure it wasn't a cable problem. Any ideas out there or anything I should try for this? Or is it time for a new TV?
Thanks in advance.
